I don't think that batteries would do what you described. They would either provide power or not. Good luck!

I've had this happen to my CZ20 when the batteries tested fine on the battery test. I switched out the batteries and it worked fine. I do know the thing doesn't like Lithium batteries and goes crazy. Another thing to check is the clamps to make sure they are tight on the battery holders.

Good Luck.

That's interesting! Are lithiums more powerful? I hope that NiMh work OK I just bought 4 recently for my CZ-20

I switch batteries out tested last night at the beach and seemed to stable out ok . but it did get stuck on a junk signal . I had to shut down and turn it back on then it was ok ... I Think it might have to go back to fisher for check up .. the md is only 2 months old .. I don't get it ... works fine inland. dry sand and wet sand .. water ,, guzz1 ...

Guzz, I have a beach that I can hardly use any detector because they go unstable, but they work fine elsewhere. It might be radio transmissions from a cell tower, police post, or any number of things at that location.

If you use NiMh make sure to get the good ones. And make sure you get a good charger like a La Crosse. The 2000-2500 dont hold up well. Stay away from the big store brand and RS.
